Sat, Jun 4, 2011from University of Bristol via ScienceDaily: Ocean Acidification Leaves Clownfish Deaf to PredatorsBaby clownfish use hearing to detect and avoid predator-rich coral reefs during the daytime, but new research from the University of Bristol demonstrates that ocean acidification could threaten this crucial behavior within the next few decades. Since the Industrial Revolution, over half of all the CO2 produced by burning fossil fuels has been absorbed by the ocean, making pH drop faster than any time in the last 650,000 years and resulting in ocean acidification. Recent studies have shown that this causes fish to lose their sense of smell, but a new study published in Biology Letters shows that fish hearing is also compromised. ...

Mon, May 30, 2011from Ottowa Citizen: Tories left oilsands data out of UN reportThe [Canadian] federal government has acknowledged it deliberately excluded data indicating a 20 per cent increase in annual pollution from Canada's oilsands industry in 2009 from a recent 567-page report on climate change that it was required to submit to the United Nations.
The numbers, uncovered by Postmedia News, were left out of the report, a national inventory on Canada's greenhouse gas pollution. It revealed a six per cent drop in annual emissions for the entire economy from 2008 to 2009, but does not directly show the extent of pollution from the oilsands production, which is greater than the greenhouse gas emissions of all the cars driven on Canadian roads.
The data also indicated that emissions per barrel of oil produced by the sector is increasing, despite claims made by the industry in an advertising campaign.
"The oilsands remain Canada's fastest-growing source of greenhouse gas pollution, and they're the subject of a huge amount of attention and scrutiny in Canada and internationally," said Clare Demerse, director of climate change at the Pembina Institute, an Alberta-based environmental research group. "So it's very disappointing to see Environment Canada publish a 500-page report that leaves out these critical numbers -- especially when last year's edition included them."

Mon, May 30, 2011from Guardian, from DesdemonaDespair: Worst ever CO2 emissions last year: less than 2 degrees C nearly impossibleGreenhouse gas emissions increased by a record amount last year, to the highest carbon output in history, putting hopes of holding global warming to safe levels all but out of reach, according to unpublished estimates from the International Energy Agency.
The shock rise means the goal of preventing a temperature rise of more than 2 degrees Celsius - which scientists say is the threshold for potentially "dangerous climate change" - is likely to be just "a nice Utopia", according to Fatih Birol, chief economist of the IEA. It also shows the most serious global recession for 80 years has had only a minimal effect on emissions, contrary to some predictions.
Last year, a record 30.6 gigatonnes of carbon dioxide poured into the atmosphere, mainly from burning fossil fuel - a rise of 1.6Gt on 2009, according to estimates from the IEA regarded as the gold standard for emissions data.
"I am very worried. This is the worst news on emissions," Birol told the Guardian. "It is becoming extremely challenging to remain below 2 degrees. The prospect is getting bleaker. That is what the numbers say." ...
